1 | Changes in version 2.26 |
2 | ----------------------- |
3 | |
4 | * New option type: 'o'. It accepts all kinds of integral numbers in |
5 | Perl style, including decimal (24), octal (012), hexadecimal (0x2f) |
6 | and binary (0b1001). |
7 | |
8 | * Fix problem with getopt_compat not matching +foo=bar. |
9 | |
10 | * Remove $VERSION_STRING for production versions. |

21 | * Remove $VERSION_STRING for production versions. |
22 | |
23 | Changes in version 2.25 |
24 | ----------------------- |
25 | |
26 | * Change handling of a lone "-" on the command line. It will now be |
27 | treated as a non-option unless an explicit specification was passed |
28 | to GetOptions. See the manual. |
29 | In the old implementation an error was signalled, so no |
30 | compatibility breaks are expected from this change. |
31 | |
32 | * Add $VERSION_STRING. This is the string form of $VERSION. Usually |
33 | they are identical, unless it is a pre-release in which case |
34 | $VERSION will be (e.g.) 2.2403 and $VERSION_STRING will be "2.24_03". |
35 | |
36 | Changes in version 2.24 |
37 | ----------------------- |
38 | |
39 | * Add object oriented interface: |
40 | |
41 | use Getopt::Long; |
42 | $p = new Getopt::Long::Parser; |
43 | $p->configure(...configuration options...); |
44 | if ($p->getoptions(...options descriptions...)) ... |
45 | |
46 | * Add configuration at 'use' time: |
47 | |
48 | use Getopt::Long qw(:config no_ignore_case bundling); |
49 | |
50 | * Add configuration options "gnu_getopt" and "gnu_compat". |
51 | |
52 | "gnu_compat" controls whether --opt= is allowed, and what it should |
53 | do. Without "gnu_compat", --opt= gives an error. With "gnu_compat", |
54 | --opt= will give option "opt" and empty value. |
55 | This is the way GNU getopt_long does it. |
56 | |
57 | "gnu_getopt" is a short way of setting "gnu_compat bundling permute |
58 | no_getopt_compat. With "gnu_getopt", command line handling should be |
59 | fully compatible with GNU getopt_long. |
60 | |
61 | * Correct warnings when the user specified an array or hash |
62 | destination using a non-lowercase option, e.g. "I=s@". |
63 | |
64 | * Correct ambiguous use of 'set' and 'reset' in the Configuration |
65 | section of the documentation. |
66 | |
67 | * Add configuration option "posix_default" to reset to defaults as if |
68 | POSIXLY_CORRECT were set. |
69 | |
70 | * Disallow "no" prefix on configuration options "default", "prefix" and |
71 | "prefix_pattern". |
72 | |
73 | * Add a section "Trouble Shooting" to the documentation, with |
74 | frequently asked questions. |
75 | |
76 | Changes in version 2.23 |
77 | ----------------------- |
78 | |
79 | * When a call-back routine issues 'die', messages starting with "!" |
80 | are treated specially. Currently, only "!FINISH" is recognised (see |
81 | the next bullet point). Other messages that start with "!" are |
82 | ignored. |
83 | |
84 | * Change 'die("FINISH") (see changes in 2.21) to die("!FINISH"). This |
85 | is an incompatible change, but I guess noone is using this yet. |
86 | |
87 | Changes in version 2.22 |
88 | ----------------------- |
89 | |
90 | * Fixes a bug in the combination of aliases and negation. |
91 | |
92 | Old: "foo|bar!" allowed negation on foo, but not on bar. |
93 | New: "foo|bar!" allows negation on foo and bar. |
94 | |
95 | Caveat: "foo|f!", with bundling, issues the warning that negation on |
96 | a short option is ignored. To obtain the desired behaviour, use |
97 | |
98 | "foo!" => \$opt_foo, "f" => \$opt_foo |
99 | or |
100 | "foo|f" => \$opt_foo, "nofoo" => sub { $opt_foo = 0 } |
101 | |
102 | Remember that this is _only_ required when bundling is in effect. |
103 | |
104 | Changes in version 2.21 |
105 | ----------------------- |
106 | |
107 | * New documentation. |
108 | |
109 | * User defined subroutines should use 'die' to signal errors. |
110 | |
111 | * User defined subroutines can preliminary terminate options |
112 | processing by calling die("FINISH"); |
113 | |
114 | * Correct erroneous install of Getopt::Long manpage. |
115 | Previous versions seem to install Getopt::GetoptLong instead of |
116 | Getopt::Long. |
117 | |
118 | Changes in version 2.20 |
119 | ----------------------- |
120 | |
121 | * Prevent the magic argument "<>" from being interpreted as option |
122 | starter characters if it is the first argument passed. |
123 | To use the characters "<>" as option starters, pass "><" instead. |
124 | |
125 | * Changed license: Getopt::Long may now also be used under the Perl |
126 | Artistic License. |
127 | |
128 | * Changed the file name of the distribution kit from "GetoptLong..." |
129 | to "Getopt-Long-..." to match the standards. |
130 | |
131 | Changes in version 2.19 |
132 | ----------------------- |
133 | |
134 | * Fix a warning bug with bundling_override. |
135 | |
136 | There's no version 2.18 |
137 | ----------------------- |
138 | |
139 | Changes in version 2.17 |
140 | ----------------------- |
141 | |
142 | * Getopt::Long::config is renamed Getopt::Long::Configure. The old |
143 | name will remain supported without being documented. |
144 | |
145 | * Options can have the specifier '+' to denote that the option value |
146 | must be incremented each time the option occurs on the command line. |
147 | For example: |
148 | |
149 | my $more = 2; |
150 | Getopt::Long::Configure("bundling"); |
151 | GetOptions ("v+" => \$more); |
152 | print STDOUT ("more = $more\n"); |
153 | |
154 | will print "more = 3" when called with "-v", "more = 4" when called |
155 | with "-vv" (or "-v -v"), and so on. |
156 | |
157 | * Getopt::Long now uses autoloading. This substantially reduces the |
158 | resources required to 'use Getopt::Long' (about 100 lines of over |
159 | 1300 total). |
160 | |
161 | * It is now documented that global option variables like $opt_foo |
162 | need to be declared using 'use vars ...' when running under 'use |
163 | strict'. |
164 | |
165 | * To install, it is now required to use the official procedure: |
166 | |
167 | perl Makefile.PL |
168 | make |
169 | make test |
170 | make install |
171 | |
172 | Changes in version 2.16 |
173 | ----------------------- |
174 | |
175 | * A couple of small additional fixes to the $` $& $' fixes. |
176 | |
177 | * The option prefix can be set using config("prefix=...") or, more |
178 | powerful, with config("prefix_pattern=..."); see the documentation |
179 | for details. |
180 | |
181 | * More 'perl -w' warnings eliminated for obscure cases of bundling. |
182 | |
183 | This version is identical to 2.15, which was not released. |
184 | |
185 | There's no version 2.14 |
186 | ----------------------- |
187 | |
188 | Changes in version 2.13 |
189 | ----------------------- |
190 | |
191 | * All regexps are changed to avoid the use of $`, $& and $'. Using one |
192 | of these causes all pattern matches in the program to be much slower |
193 | than necessary. |
194 | |
195 | * Configuration errors are signalled using die() and will cause the |
196 | program to be terminated (unless eval{...} or $SIG{__DIE__} is |
197 | used). |
198 | |
199 | * Option parsing errors are now signalled with calls to warn(). |
200 | |
201 | * In option bundles, numeric values may be embedded in the bundle |
202 | (e.g. -al24w80). |
203 | |
204 | * More 'perl -w' warnings eliminated for obscure cases of bundling. |
205 | |
206 | * Removed non-standard version number matching. Version 1.121 is now |
207 | more than 1.12 but less than 1.13. |
208 | |
209 | Changes in version 2.12 |
210 | ----------------------- |
211 | |
212 | * A single question mark is allowed as an alias to an option, e.g. |
213 | |
214 | GetOptions ("help|?", ...) |
215 | |
216 | Changes in version 2.11 |
217 | ----------------------- |
218 | |
219 | * User linkage may be an object, provided the object is really a hash. |
220 | |
221 | For example: |
222 | |
223 | { package Foo; |
224 | sub new () { return bless {}; } |
225 | } |
226 | |
227 | my $linkage = Foo->new(); |
228 | |
229 | GetOptions ($linkage, ... ); |
230 | |
231 | * Some bug fixes in handling obscure cases of pass-through. |
232 | |
233 | Changes in version 2.9 |
234 | ---------------------- |
235 | |
236 | * A new way to configure Getopt::Long. Instead of setting module local |
237 | variables, routine Getopt::Long::config can be called with the names |
238 | of options to be set or reset, e.g. |
239 | |
240 | Getopt::Long::config ("no_auto_abbrev", "ignore_case"); |
241 | |
242 | Configuring by using the module local variables is deprecated, but |
243 | it will continue to work for backwark compatibility. |
244 | |
245 | Changes in version 2.6 |
246 | ---------------------- |
247 | |
248 | * Handle ignorecase even if autoabbrev is off. |
249 | |
250 | * POD corrections. |
251 | |
252 | Changes in version 2.4 |
253 | ---------------------- |
254 | |
255 | * Pass-through of unrecognized options. Makes it easy to write wrapper |
256 | programs that process some of the command line options but pass the |
257 | others to another program. |
258 | |
259 | * Options can be of type HASH, now you can say |
260 | |
261 | --define foo=bar |
262 | |
263 | and have $opt_define{"foo"} set to "bar". |
264 | |
265 | * An enhanced skeleton program, skel2.pl, that combines the power of |
266 | Getopt::Long with Pod::Usage. |
267 | Module Pod::Usage can be obtained from CPAN, |
268 | http://www.perl.com/CPAN/authors/Brad_Appleton. |
269 | |
270 | Possible incompatibility in version 2.4 |
271 | --------------------------------------- |
272 | |
273 | Previous versions of Getopt::Long always downcased the option variable |
274 | names when ignorecase was in effect. This bug has been corrected. As a |
275 | consequence, &GetOptions ("Foo") will now set variable $opt_Foo |
276 | instead of $opt_foo. |
